Hello, it’s Takuya here. This is a story about my experience on my solo product called Inkdrop — a Markdown note-taking app with built-in cloud sync. It is a SaaS that earns $3,200 per month from 600 customers now, with pricing $4.99/mo or $49.9/yr. Thanks to its profit, I have had no freelance works this year. Cool. I really appreciate all your support!
